One plant growth regulators

Technical field

The invention belongs to plant growth regulator field, relate to a kind of plant growth regulator containing cloxyfonac, fluoridamid, gibberellin and eugenol.

Technical background

Cloxyfonac (cloxyfonac-sodium), the chloro-2-p hydroxymethylphenoxyacetic acid of chemical name: 4-, molecular formula: C ₉h ₉clO ₄, CAS accession number: 6386-63-6, belongs to aryloxy acetic acid class plant growth regulator, has the effect of class growth hormone, can urge to spend short fruit.

Fluoridamid (fluoridamid), chemical name: 3 '-(1,1,1-trimethyl fluoride sulfonyl amido) to the first and second anilids, molecular formula: C10H11F3N2O3S, CAS accession number: 47000-92-0, dwarfing plants agent can be used as, suppress the growth of plant stem, also can accelerate fruit maturation and improve sugar content, also to part weeds, there is growth inhibitory effect.

Gibberellic acid (gibberellic acid, GA3) is a kind of broad spectrum activity plant growth regulator, can promote that plant cell extends, make blade increase, fruit growth, seed dormancy can also be broken, accelerate to sprout, change female, male flower ratio, control the sex etc. of flower.

Eugenol (eugenol), chemical name: Coryophyllic acid, molecular formula: C ₁₀h ₁₂o ₂, CAS accession number: 97-53-0, is a kind of sterilization component separated from plant, is pharmaceutically can be used in antibacterial, anti-inflammatory, agriculturally can be used in the control of the crop pests such as gray mold, banded sclerotial blight, sigatoka.

At present, the technology of composite for different plant growth regulator use is generally used in agricultural production, but, plant growth regulator huge number, physicochemical property, action character etc. are different, inappropriate compound scheme not only can not play the effect of its Promoting plant growth, even can cause the bad results such as poisoning.Therefore, how to select suitable plant growth regulator to carry out reasonably composite, making it produce optimum efficiency and avoid plant growth regulator on the impact of plant itself, is the problem during this area is still explored.

Summary of the invention

For the problems referred to above, the invention provides a kind of safe and effective plant growth regulator composition, by cloxyfonac, fluoridamid, gibberellic acid and eugenol are carried out mixture according to certain amount, each composition is worked in coordination with mutually, can remarkable Promoting plant growth, improve fruit yield and quality.

This application provides a plant growth regulators, the percentage by weight of its active component is: cloxyfonac 1.5 ~ 8%, fluoridamid 0.2-4%, gibberellic acid 0.04-0.2%, eugenol 10-40%; Be preferably: cloxyfonac 4-6%, fluoridamid 0.5-2%, gibberellic acid 0.1-0.18%, eugenol 10-40%; More preferably: cloxyfonac 4.6%, fluoridamid 1.45%, gibberellic acid 0.13%, eugenol 10-40%.

Plant growth regulator of the present invention can be prepared into the common formulations of agriculture field, comprises agriculturally acceptable auxiliary agent kind accordingly.

Preferably, the formulation of described plant growth regulator is liquor, and described auxiliary agent is solubilizer and solvent, and the percetage by weight that described solubilizer accounts for plant growth regulator composition is 6-40%; Described solubilizer is the solubilizer agriculturally commonly used, and is preferably one or both in polysorbas20, polysorbate40, polyoxyethylene nonylphenol ether, castor oil polyoxyethylene ether or naphthalene sulfonic acid-formaldehyde condensation product sodium salt.Described solvent is the solvent agriculturally commonly used, and is preferably methyl alcohol, ethanol, isopropyl alcohol or ethyl acetate, is particularly preferably ethanol.

Plant growth regulator of the present invention can conventionally be prepared from.

Concrete, described method comprises: each component is added solvent respectively, fully stirs, and leaves standstill, obtains plant growth regulator, the corresponding multiple of dilute with water as required during use.

The present invention also protects the application of described plant growth regulator on solanaceous vegetables or fruit tree.

The concrete using method of described plant growth regulator is: carry out first time spraying seedling stage plant, dilute 200 times of liquid sprayers and evenly spray to complete stool; Carry out second time spraying in initial bloom stage, dilute 150 times of liquid, with sprayer from plant bottom upwards even spraying, make medicament contact bud as far as possible; Carry out third time spraying in full-bloom stage, dilute 200 times of liquid even spraying, make medicament contact flower fringe as far as possible.High temperature and drought weather is avoided in dispenser operation.

Plant growth regulator provided by the invention can produce following beneficial effect:

(1), can effectively break crop growth dormancy, promote to bear fruit, increase yield, regulate nutriment to distribute, improve the sugar content of fruit, thus remarkable fruit quality;

(2), eugenol can effectively prevent and treat the plant diseases such as grey mold, line is withered, epidemic disease is mould, reduces disease to the invasion of plant, thus greatly improves output;

(3), different types of active component carries out composite according to a certain percentage, and produce synergy each other, compared with single dose, result of use improves greatly.
